LOOKING MEANS.

. Specification of Letters Patent. Patented Nov. 23, 1920.

Application filed June 12, 1917. Serial No. 174,192.

To all whom it may concern:

Be it known that I, ERNEST D. ANDERSON, a citizen of the United States, and resident of New York cit borough of Manhattan, in the county of ew York andState of New York, have invented certain new and useful Improvements in Locking Means, of which the following is a specification.

'l he object of my invention is to provide cheap and simple means to prevent displacement relatively one to another, of juxtaposed material in a direction substantially parallel to the planes of said material.

In carrying out my invention I provide two or more juxtaposed layers of material, such as sheets of paper, metal or the like, and I form a slit through such layers of material and bend such layers on one or both sides of the slit to cause edge portions of said material at suchslit to oppose to prevent displacement of the layers of the material in certain directions. 7

My invention may be embodied in different forms of devices, such as for securlng sheets of material of any desiredsize from displacement by sliding relatively to each other, or in receptacles or bags for retalning their mouths closed, and in other relations. My invention further comprises novel details of improvement that will be more fully hereinafter setforth and then pointed out in the claim. I 1

Reference is to be had to the accompanying drawings forming part hereof, wherein, Figure 1 is a perspective view illustrating two sheets of material embodying my improvements; Fig. 2 is a perspective view of a receptacle or bag constructed in accordance with my invention; Fig. 3 is an enlarged crosssection substantially on the line 3, 3, in

Fig. 2; Fig. 4 is a plan View of a blank from which the receptacle shown in Fig. 2 may be made, and Fig. 5 is a perspective View illustrating the manner of folding the-blank for the production of said receptacle.

A plurality of juxtaposed layers or sheets of material are indicated at 1, 2, shown placed one'agai'nst the other, which layers are slit through at 3, and said layers are bent sidewise adjacent to said slit, being shown. bent in opposite directions at 4, 5, to one, side of the plane of the layers, although one of such bends will suffice for some purposes.

Such slitting and bending of the layers of the material has the effectto cause the inner edges of the bent portion to oppose inner edges of the opposite portion adjacent to the ends of slit 3, mediate positions oppose,

where such edges may which prevents the displacement of as well as at any inter the layers of material laterally or edgewise relatively one to another, as in the directions of-the arrows in Fig. 1.

The arrangement described may be useful in different relations to prevent relative displacement of layers of juxtaposed material. I have illustrated my invention embodied in a receptacle or bag adapted to contain food products or other goods, bag may'be made from a single sheet of paper or other suitable material folded to produce the desired receptacle. The receptacle or bag is shown having a bottom 6, opposing side walls 7, 8, and intermediate end walls 9 adapted to fold between said walls. Such receptacle or bag may be made by folding a blank indicated at 10, which may be made of paper. Said blank may be made waterproof, if desired, by impregnating the same withsui-table wax or paraffin, or applying one ormore layers of wax or paraflin thereon. In the example illustrated. the blank 10 is shown provided with spaced centrally disposed score lines 11, '12, between which the bottom 6 and the end walls 9 are formed, and with spaced transverse score lines 13, 14 between which and the lines 11, 12, the portions 15, 16 of the sides may be formed. Said blank is also shown having diagonal score lines 17, whereby corresponding corner webs 18, 19 are formed, which provide outer layers of the sidewalls of the receptacle when the blank is folded for setting up the receptacle or bag. The latter may be set up by folding the blank on said score lines in the manner illustrated in which receptacle or Fig. 5, so that when the parts are all folded together the receptacle or bag may appear bent transversely along the fold line indi-.

cated at 20 (Fig. 2), providing a laterally extending mouth portion 21, comprising sevv that are between the slit 22 and the edges 23 are bent to one side of the plane of por-- tion 21, as by being bent downwardly at 24. The layers or Webs of the projectin parts 21 that are between the slit 22 and t e fold may also be bent to one side'of the plane of portion 21, as by being bent upwardly at T 25. While the bend at 24 may suflice forsome purposes, it may be preferable in some receptacles to bend the layers in opposite directions, as indicated in Fig. 2. Such slitting and bending of the material of the projecting portion 21 at the mouth of the re- Q ceptacle or bag has the effect to cause the inner edges of the layers of the bent portions 24 to oppose the inner edges of the layers of the opposite portion 'at the ends of slit 22, as well as at any intermediate positions where such edges may oppose, which prevents displacement'of the layers of projecting portion 21 in a lateral or edgewise direction, as in the direction of the arrows in Fig. 2, and the abutting of the opposed wall portions or sides of the receptacle prevent displacement of said layers in an'opposite direction In the example illustrated in Fig. 3 several of the layers of projecting portion 21 of the receptacle ZtIG'ShOItBI than other layers, so that the slit 22 passes through the latter layers only. By the means described the layers of the lateral projection portion 21 of the receptacle or bag month are retained from spontaneous opening in the directions indicated, and the fold at 20 serves to vent the contents from sliding out.

fold may be squeezed or compressed or given a sort of back set to form a rather sharp edge to aid in preventing the outflow of the contents of the receptacle, and to aid in greaid

causing the projecting portion 21 thereof to remain in a laterally disposed position.

The construction described affordsanexceedingly-simple and yet eflicient means of preventing displacement of superposed or juxtaposed layers of material, without re- I receptacle when charged is adapted to be inclosed within a carton for transportation, and since the layers are" held securely together moisture is excluded from the receptacle.

Having now described my invention what 1 claim is 7 I i.

A receptacle comprising a single piece of material folded to form a bottom, side walls and ends, and having corner portions folded and lapped along corresponding side walls,

said material at the 'mouth portion being located close together and folded providing a lateral pro'ection of layers of material, said layers 0 material having a slit theret-hrough extending in the direction of the outer edges of said material and distant therefrom, said folded material having layers on one side of the slit deflected from the plane of the layers on the other side of said slit presenting edges of the deflected layers in register with other layers on the opposite side of the slit, said edges extending in the general direction of the outer edges of said mouth to prevent said layers from slipping in a lateral direction upon one another.
